A Developmental Study on English Proficiency Test via the Internet

1. 本研究背景：2004年，本课题组利用某私人研究机构开发的测试引擎，通过互联网开发了一个基于计算机的英语水平测试实验。然而，这项测试有一些障碍。(1)即使团队成员为了学术目的使用发动机，研究小组也必须每年支付租金。(2)无法将部分测试项目添加到该测试的测试项目池中。为了扩大测试的测试项目池，必须将测试项目池中的所有测试数据替换为所有新的测试数据，包括池中的新测试项目和当前测试项目。这项研究的结果(1)用一个新的测试引擎替换测试引擎，这个测试引擎是由这个团队的成员，菊池博士开发的。更换后，18名学生同时参加了笔试和机试。这两个测试的测试项目是从同一测试项目池中取出的。相关系数为0.90。(2)测试系统的修改：对系统进行了修改，在不替换所有数据的情况下，可以将一些新的测试项目添加到池中。

1. Background of this research : In 2004, this research group developed an experimental computer based English proficiency test via the Internet using a test engine which had been developed in a private research institution. However, the test had some snags.(1) The research group had to pay the rental fee for the engine every year even when the member of the team uses it for academic purposes.(2) It is impossible to add some test items into the test item pool of the test. In order to enlarge the test item pool of the test, all the test data in the test item pool had to be replaced with all the new test data which include new test items and current test items in the pool as well.2. The results of this study(1) The replacement of the test engine with a new test engine which is developed by a member of this team, Dr. Kikuchi. After the replacement, eighteen students took the both tests of paper-based tests and computer-based tests. The test items of the both tests were taken out from the same test items pool. The correlation coefficient turned out 0.90.(2) The modification of the test system: The system was modified so that some new test items could be added into the pool without replacing all the data.
